Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

As seen in the picture above, you’ll sacrifice 2 analog pins, but if you happen to need IO and have an extra Arduino lying around, this could really help.

Arduino created a Renesas RA4M1 microcontroller board in its Nano form-factor. Called Nano R4, it follows the Uno R4, the first Arduino to use the RA4M1. Episode 13 of our podcast CHIIPs is out now, ...
